Trial Outcomes & Findings for Evaluating High Flow Humidification Therapy in Patients With Cystic Fibrosis (NCT NCT02129803)
NCT ID: NCT02129803
Last Updated: 2021-01-06
Results Overview
The Cystic Fibrosis Questionnaire-Revised (CFQ-R) is a validated health-related quality of life measure for CF that meets US Food and Drug Administration psychometric requirements for patient reported outcomes. It contains both generic and CF-specific scales and has demonstrated responsiveness in previous clinical studies. Scores range from 0 to 100 with higher scores indicating better health.

SECONDARY outcome
Timeframe: 10 minutesPopulation: We were unable to collect sputum samples from the participants
Sputum is collected during pulmonary function test (PFT) to later measure the biophysical properties of cystic fibrosis sputum.
